#619 superLU fails to notice a matrix is singular sometimes, #1351

Open nikhilgupta10 opened 7 years ago

nikhilgupta10 commented 7 years ago

superLU occasionally iterates on a matrix that has obviously become singular. fault_check can be put into the system to supplement this check, but there may be options inside superLU to fix it.

There do not appear to be any superLU flags to make it more obust. Deferring this to 3.0 so as more examples pop up, we can handle them.
